Used air drier value?

[BigE]

What is the most you would pay for a used speedaire 4xx34 air drier? It supposedly works. It came from a fleet shop that is replacing some of its equipment.

If you can confirm it works OK, it should be worth a few hundred. If you can't confirm operation, then not much! (IMHO, and I'm one cheap *******!)
